.CARBON COPYING-BOOK.

SPECIFICATION forming part oit Letters Patent No. 691,506, dated January 21, 1902. Application filed February 3, 1900. Serial No. 3,786. (No modehl' T0 all whom it may concern:

Be it known that we, ALBERT R. TURK and BELA G. MERRILL, citizens of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Carbon Copying- Books, of which the following is a specification.

Our invention relates to improvements in carbon copying-bookmand pertains especially to that class of books which are provided with removable covers adapted to be used successively on diti'erent books and a carbon-sheet adapted to be used successively between the leaves of each book. The term book is used in this connection to designate any package or block of sheets, memorandum-blanks, or papers such as are commonly used for manifold order or record purposes.

The object of our invention is to provide means for attaching the carbon-sheet to the book-cover and supporting the same from a line near the bound end ofthe book in amanner to facilitate the interposition of the carbon-sheet between successive sets of leaves, to facilitate the'substitution of one sheet for another, and to permit the adjustment of the carbon-sheet in a position to meet the requirements of books of various styles.

In the following description reference is had to the accompanying drawings, in which- Figure 1 is a perspective view of our invention with an order-book of ordinary style inserted in the covers in position for use and illustrating the manner iu which the device is manipulated to interposethe carbon between the sheets. Fig. 2 is a view of the carbon-holder removed from the cover. Fig. 3 is a detail view of the carbon-sheet clamp.

Fig. 4 is a sectional View of a portion ofv the clamp drawn longitudinally through the sheet-engaging points.

Like parts are identified by the same reference-letters throughout the several views.

A and B are the respective covers of our improved book.

C is the block or package of sheets composing the leaves of the book as ordinarily used, and D is a rod pivotally secured to one of the covers intermediate of its ends and forming a part of the carbon holder or carrier. This rod is preferably secured to the cover at or near the center of one of the side edges, a convenient method of attachment being to extend the rod transversely through the material composing the cover, a hook or knob E being then formed on the end of the Wire to prevent its withdrawal.

The carbon-clamp F is formed of a fiat strip of sheet metal doubled upon itself and having one end permanently secured to the rod D and the other end formed into a hook G, adapted to engage the rod D elastically when the clamp is closed. The material of which the clamp is composed is dented inwardly at the jaws are pressed together and the hook G rengaged with the rod D.

The pivotal end rod or transverse portion of the bar D, together withisaidv bar and the carrying bar or clamp for the carbon-sheet, constitutes a carrier for the vcarbon-sheet, which adequately supports the latter, While leaving one side open for a free and uninterrupted access to the carbon-sheet in entering' or withdrawing the same for use or for the purpose of manipulating the memorandum sheets or blanks to adjust them under and above the carbon-sheet without removing the latter. Where the unused sheets are supported by the cover A, as shown in Fig. l, and the carbon-sheet, together With the recordsheets, is supported on the cover B, with the carbon-sheet held by the carrier at the end next to the binding of the sheets, the unused sheets maybe readily manipulated under and above the carbon-sheet without removing the latter from the book. This result -is accomplished by slightly lifting the attached end of the carbon-sheet by the pressure of the thumb on the bar D, while the copy-sheet or blank is brought over by a inger of the other hand (or a pencil) and stripped or drawn under the carbon-sheet by a free-hand movement, all as clearly illustrated in said figure. The other blank or receiving-sheet is then brought over and dropped on the upper surface of the carbon-sheet, when the book is ready for the entry. It is obvious, therefore, that this construction will greatly facilitate the use of the book, for no time is consumed in adjusting the carbon-sheet.

It will be observed that the clamp F is supported from the rod D in a position to extend transversely of the cover near one end, and as the pivot is located at or near the center of the cover the rod may be swung to adjust the carbon-holder in position for `use at either end of the cover. The same covers and carbon-holders may therefore be used both for that class of books in which the binding of the book is coincident with the iexible connection between the covers and forthat class of books in which the bindingis coincident with the outer end of the cover.

In use the book is heldin the hand, as shown in Fig. 1, with the unused leaves resting on the cover A. The bar D is raised by the thumb or nger, and the copy-sheetis brought over by means of the finger or a pencil held in the other hand of the user and drawn under the carbon-sheet, as also illustrated in Fig. 1. The next sheet is then brought down upon the carbon-sheet, when the entry made there.- on will be transposed to the sheet lbelow in the usual manner. VVheu the device is used for a book or block of sheets bound at the outer end, the bar D is swung over to adjust the-carbon-clamp, also at the outer end, when the clamp is opened, as heretofore explained, and the carbon-sheet removed and reinserted with the carbonized su rface u uderncath, when the book is ready for use.

We attach great importance tothe fact that with this device the carbon-sheet clamp may be located at or near the bound end of the book, with the free end of the sheet coincident with the free ends of the book-leaves, and that the leaves may be adj usted to receive the carbon imprint Without removing th'e carbon-sheet from the book. Where books are bound at the outer ends of the leaves, the carbon-holder may, if pivoted at the center of the cover, be reversed in position, as above explained, thus supporting the carbon-clamp at the bound end of a book of this class also. The carbon-sheet being supported from a bar located at only one side of the cover, it is obvious that the bar will not interfere with the manipulation of the leaves in the manner described.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

l. Inamanifolding-book, the combination of a cover; a pad or block of memorandumleaves, bound at one end; a support mount ed on. the cover, said support comprising a single side bar pivotally secured to the cover atulone end, vwith the other end projecting from said pivot along one side of the memorandum-block toward the bound end of the memorandum-block, and free to oscillate on said pivot perpendicularly to the plane of the cover; a carrying end bar rigidly secured to the side bar in a position to project across the memorandum-leaves, near their bound end, and supporting a carbon-sheet, whereby such sheet may be freely lifted by the pressure of the thumb or finger on the side bar, while the other side is leftopen for an uninterrupted passage of a finger or pencil, in manipulating the copy-sheet, and adjusting it under the carbon sheet without removing the latter from the book.

2. The combination with a book-cover; of a barpivotally secured thereto; and a strip of resilient material secured at one end to the bar and doubled upon itself, with its free end formed into a hook adapted to engage said bar, said strip being dented inwardly at intervals to form points adapted to engage the carbon-sheet, and said points being arranged in sets of three, with the intermediate point opposing the other two of each set.

3. In a manifolding-book, the combination of a cover; a pad or'block of memorandumleaves; a support mount-ed on the cover, substantially midway of the ends thereof, said support comprising a single side bar pivotally secured to the cover at one end, with the other end projecting toward the bound end of the memorandum-block, and free to oscillate perpendicularly to the plane of the cover; a carrying end bar rigidly secured to the side bar in a position to project across the memorandum-block near its bound end, and arranged to support the carbon-sheet, whereby the sheet may be freely lifted by the pressure of the thumbl or ingerron the bar, at one side of the cover, while the other side is left open for an uninterrupted passage of sa finger or pencil in manipulating-the copy-sheet, and adjusting it under the carbon-sheet, without removing the latter from the book.

4E. In a manifolding-book, the combination ofa cover, a pad or block of memorandum blanks or papers; a carrier or support mounted on the cover substantially midway of the ends thereof, said carrier or support comprising a single side bar, a pivoting end bar for attachment to the cover, and a carrying end bar for attachment thereto of the carbonsheet, leaving an open side for a free and uninterrupted access to the carbon-sheet in enitering and withdrawing the same for use; and

a carbon-sheet detachably connected to the carrying end bar.

In testimony whereof we aix our signatures in the presence of two witnesses.
